In order to remove wash liquor from the laundry care device after the laundry care process, conventional laundry care devices also have an evacuation system. In addition to the pumping system and the pumping out system, further conveyor systems for pumping washing liquor may be present in the laundry care appliances. For the pumping system, the pumping system and the other conveyor systems pumps are needed to ensure effective pumping of the wash liquor.
